Arizona Cardinals cornerback Patrick Peterson is being evaluated for a concussion after a violent collision with a teammate and Philadelphia receiver Jeremy Maclin on Sunday.

The injuries occurred late in the second quarter, when Peterson and teammate Deone Bucannon collided with Maclin on a pass play.

Peterson lay face down after the hit before rolling over to his back. Medical personnel checked on Peterson, who eventually sat up and gingerly walked toward the sideline. He was then led to the locker room to be evaluated for a concussion.

Maclin lay on the field for a few seconds before heading to the sideline. He returned later in the quarter after clearing concussion protocol.
